I have now been the 3rd bottle of it in use, and I'm thrilled! I always had a sher dry skin, which is also on the side of the nose always "flaked" if for example: in winter, the air was very dry. Since I used the serum is meione skin uniformly tender and I have no more dry patches. Also after Autragen equal a "freshness" to feel what I especially in the morning very appreciate!
